Answer:

Question: solve the equation 27 = 15 + n

Step-by-step explanation:

Answer: n = 12

Solution: Step 1: Move the variable to the left hand side and change its sign.

= 27 - n = 15 and then, move the expression to the right hand side and change its sign.

= - n = 15 - 27

Step 2: Calculate the difference.

- n = 15 - 27 is equal to - n = - 12.

Step 3: change the signs on both sides of the equation.

And the final answer is, n = 12
